About O31.0

O31.0 is the ICD-10-CM diagnosis code for Papyraceous fetus. It belongs to category O31 (complications specific to multiple gestation), block O30-O48 (maternal care related to the fetus and amniotic cavity and possible delivery problems) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within O31 (complications specific to multiple gestation), O31.0 is specifically for Papyraceous fetus. Related codes cover Continuing pregnancy after spontaneous abortion of one fetus or more (O31.1), Continuing pregnancy after intrauterine death of one fetus or more (O31.2), Continuing pregnancy after elective fetal reduction of one fetus or more (O31.3), Continuing pregnancy after vanishing twin syndrome of one fetus or more (O31.4) and other complications specific to multiple gestation (O31.8).

Codes in this range require a 7th character: 0 for not applicable or unspecified, 1 for fetus 1, 2 for fetus 2, 3 for fetus 3, 4 for fetus 4, 5 for fetus 5 and 1 more. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

7th character

One of the following 7th characters is to be assigned to each code under category O31. 7th character 0 is for single gestations and multiple gestations where the fetus is unspecified. 7th characters 1 through 9 are for cases of multiple gestations to identify the fetus for which the code applies. The appropriate code from category O30, Multiple gestation, must also be assigned when assigning a code from category O31 that has a 7th character of 1 through 9.
